A music video for the song was directed by Nigel Dick and shot at in various places of Los Angeles including the Orpheum Theatre. It depicts the Pussycat Dolls performing the song on a rehearsal stage while preparing for a tour. To further promote "Stickwitu", the group performed the song during several televised appearances, and in two of their concert tours, their most recent, at the Doll Domination Tour (2009).

"Stickwitu" was written by Franne Golde, Kasia Livingston and Robert Palmer while the production was handled by Ron Fair and co-produced by Tal Herzberg who also engineered the song. Mike Hogue assisted in the mix engineering. The group's vocals were recorded by Mike "Angry" Eleopoulos. Fair also arranged, and conducted the strings played by the PCD orchestra, which were recorded by Allen Sides. The original drum programming was done by Palmer. The song was finally mixed by Peter Mokran at The Record Plant. Fair additionally played harmonica, piano, organ and Rhodes while Herzberg and Cori Jacobs handled the bass and Rhodes respectively.[1] In July 2005 MTV News reported that "Beep" featuring will.i.am was a "potential second single;"[2] however that later changed and "Stickwitu" was sent to contemporary hit radio in the United States on September 26, 2005 as the second single.[3]

"Stickwitu" received mixed reviews from critics. Chuck Taylor from Billboard magazine was surprised of the song and praised it for being "beautifully sung, craftily produced and refreshingly gimmick-free." He went on to praise the "catchy" chorus and noted that the "track is unlike anything else on the air."[7] Kalefah Sanneh of The New York Times wrote that "Stickwitu" "might be even better" than 'Don't Cha'".[6] Paul Scott of Stylus Magazine agreed with Sanneh adding that it's "pretty enough but just sort of mills around without getting up the courage to go [over the top], and that's actually a good thing."[8] John Murphy of musicOMH wrote that although "it's nicely sung, it doesn't particularly stick in the mind very much." He continued the "Dolls' voices do well at harmonies" but noted that "none have a particular strong vocal."[4] Spence D. shared the same sentiment with Murphy adding that Scherzinger "never really presents anything that could come close to being called a signature sound."[9]

Kevin Courtney of the Irish Times gave "Stickwitu" two out of five stars noting that "they don’t want to be one-hit wonders."[10]Stephen Thomas Erlewine was not impressed with the song, saying that "PCD seems like it will be that rare thing: a mainstream club/dance album devoted to nothing but dance songs. Then, reality comes crashing in with the fourth song, 'Stickwitu', the inevitable romantic slow jam whose sappiness undercuts the joyous carnal celebration of the first three songs.[11] Sal Cinquenmani from Slant Magazine found the song difficult to take seriously. He said "the album's ballads ('Stickwitu' and 'How Many Times, How Many Lies'), though sufficiently un-icky, are still difficult to take seriously when followed by a song that begs a man to 'loosen up my buttons'."[12] Kat Bein of the Miami New Times wrote that it's "in the running for most trite lyrics of all time."[13] Nathan Rabin from The A.V. Club described the song as a "saccharine, sleepy ballad."[14] Writing for Sputnikmusic Nick Butler described "Stickwitu" as a "limp, lifeless ode." However he did noted that "it's nowhere near as sickly or disgustingly submissive and sexist as something like Destiny's Child's 'Cater 2 U'."[15]

The music video for "Stickwitu" was shot over two days in different places of Los Angeles including the Orpheum Theatre.[30]Nigel Dick was chosen to direct the video as the group wanted to maintain its momentum garnered from "Don't Cha".[31] Dick admitted that he felt pressure to deliver. "This video establishes the way they want to be seen from now on. But that's the way it's always been for me. I've been very lucky in my career to do videos for people that are very crucial in artist's careers."[30] Nicole Scherzinger elaborated that the music videos' goal was to make each girl identifiable by showing different sides of their personalities. "This video shows much more vulnerability. Part of it is [showing] the strength to do what we do [as performers]; the other is to show that we have our vulnerabilities in life with trying to hold up relationships while we're on the road. We wanted to make sure that each of us was identifiable in this video, that you got to know each girl a little bit more, and get to see what we're like on and off tour." The music video premiered on MTV.com, on October 13, 2005.[31]

The video was described as "a day in the life of the Pussycat Dolls on the road."[31] Dick added that the music video is "a photographic [rendition of] the life of the Pussycat Dolls: traveling around, getting ready for gigs, being on the tour bus, doing a photo session, waking up in a motel, talking to the boyfriend on the phone, sound-checking. It's informal but beautiful. It's not rock and roll; it's the urban-pop world."[30] The video is inter-cut with scenes of the Pussycat Dolls performing "Stickwitu" in a rehearsal stage.

On December 2005, the group performed for the annual KIIS-FM Jingle Ball wearing "festive candy-cane-striped belly shirts and red-and-green capri pants." The set list included "Don't Cha", "Stickwitu" and "Wait a Minute".[32] On June 30, 2006 the group performed "Don't Cha", "Buttons" and "Stickwitu" on Good Morning America as part of its Summer Concert Series.[33] On July 7, 2007 the Pussycat Dolls together with other artists performed at the Live Earth Concerts, which were held to raise awareness of global warming. They performed "Don't Cha", "Stickwitu", and "Buttons".[34]

"Stickwitu" was included on the group's first live albumLive from London (2006).[35] The Pussycat Dolls also performed "Stickwitu" throughout their second tour, Doll Domination Tour (2009). Alex Macpherson of The Guardian praised Scherzinger's "inventive and versatile" vocals which are "gently crooning the sweet ballad."[36] Scherzinger has performed "Stickwitu" as part of a Pussycat Dolls medley throughout Scherzinger's first solo tour solo tour in support of her debut studio album, Killer Love (2011).[37]
